Overview
This chapter describes the RLON-01 operation on a LONWORKS
®
network.
General
In LONWORKS
®
networks, the network design emphasis is on
designing the network variable connections. The connection
design determines the amount of data flow between different
nodes, thus determining the decision of transmission media and
network topology overall in the network.
In designing the connections, the selection of protocol services is
also crucial when determining the network data flow. By default,
the network connections use acknowledged messaging with a
certain retry count. This can, however, be changed by the
installation tool to optimize the overall network performance.
To be able to realise the required operation of the whole system, a
clear picture of the capabilities of individual nodes is needed.
These capabilities are determined by the network variables.
LonMark objects
The RLON-01 includes two objects, a node object and a drive
object. The node object is used to control the drive object. The
drive object realises the L
ONMARK
®
Functional Profile: ‘Variable
Speed Motor Drive Version‘, 1.1. The profile defines a set of
network variables and configuration properties. In addition, the
drive object includes a set of manufacturer defined network
variables and configuration properties that are defined in order to
realise functions only applicable for ABB Drives.

- If one of the drive parameter values marked with not using the corresponding configuration network variable is changed the rlon 01 needs to be re initialised in order to update it s value for example if the stop mode parameter is changed with the control panel the rlon 01 needs to be either rebooted or temporarily disabled for the rlon 01 to read the updated value from the drive the same applies if one of the marked parameters using the nciparvalue configuration parameter is changed 34
